1, prepare the original stone.
2. Roughly grind with 180 mesh sand strips, and all the skins will be ground off. Some people will leave a back, the first is less, the second is original, depending on personal preferences.
3. Then use 360-mesh sandpaper to polish it, in order to repair the scratches generated by the previous sand strips, and then roughly trim the overall outline.
4. This time, 1200 mesh sandpaper is used to remove the big scratches produced by 360 mesh before repairing.
5. Use 2000 mesh sandpaper to polish it again. There are basically few scratches caused by 1200 mesh sandpaper.
6. Now polish it again with 3000 mesh sandpaper. Sandpaper is added layer by layer, the main purpose is to cover the previous scratches. After polishing with 3000 mesh sandpaper. I can hardly see any scratches.
7. Polishing, there are many kinds of polishing, such as polishing powder, nail strips, polishing paste, toothpaste, etc. Toothpaste can be used directly at home. Touch the amber lightly. Then wipe it with a towel, and it will take about a few minutes to achieve a mirror effect.
8. The finished product is discharged from the furnace, as shown in the figure below.

Precautions:
1. Before gluing, clean the gems and sticky sticks;
2. When preheating gems, sticking sticks and heating viscose, don't be too close to the flame to avoid cracking and colloid aging of gems due to excessive heating;
3. When bonding, try to make the bottom of the gem perpendicular to the rod axis, and the glue should not exceed the outer edge of the blank;
4, after bonding, wait for its natural cooling before processing.
Process requirements:
1, leave a certain machining allowance, the shape of the circle is basically parallel to the drawn outline, and there should be a machining allowance of about 0.5 mm
2. In order to prevent the bottom edge from being damaged, it is necessary to grind a small inclined plane on the bottom edge after grinding the waist shape. Generally, the oblique angle is 45 and the thickness is 0.5 mm ..
